Oh, no. I use floating IPs for actually real public IPs. But now, that you mention the pools, well, I would have to assign one floating IP to at least TWO KVM instances. Hm, Pacemaker/Corosync *inside* the VM will add the Service-IP to the local ethernet interface, and thus, the outside OpenStack

Hey all, I would like to setup a highly available service *inside* two KVM instances, so I have created a security group to contain all required service ports, so clients can connect to either VM and that works. And both instances have their own designated IP address, provided by nova itself.
